Question
Chapter 28.4, Problem 1CC
Summary Introduction
To explain: The way in which cysts are involved in the spread of harmful algae and disease-causing parasitic protists.
Introduction: Protists are found in a variety of habitats such as the ocean, hot springs, polar areas, host organisms and so on. They generally reproduce by asexual means. They produce a structure known as cysts during their reproduction. Cysts are composed of only one cell. They are made up of a thick cell wall.

O The alga photosynthesizes produce sugars the fungus is able to use, while the fungus keeps the alga safe from being eaten.
O The fungus serves as the substrate the alga needs to perform mitosis, while the alga produces enzymes the fungus needs for decomposition.
O The fungus produces the sugars the alga uses for cellular respiration, while the alga provides a safe place for the fungus to live.
O The alga offers camouflage to the fungus against herbivory, while the fungus secretes toxic substances that release nutrients from the rocks to the alga.
Mark this and return
A lichen is an organism that is actually made of both a fungus and an alga. These organisms live together on rocks and other hard surfaces. How does
a lichen demonstrate obligate mutualism?
